Fragment-specific internal fixation of distal radius fractures

Restoration of articular congruity and maintenance of a stable, anatomic reduction are critical in the treatment of distal radius fractures. Internal fixation of these injuries can be challenging, owing to the limited soft-tissue coverage, proximity of adjacent tendons and nerves, and presence of small, often osteoporotic fracture fragments. Fragment-specific fixation refers to the use of limited surgical incisions and low-profile, anatomically contoured implants to provide rigid fixation of each individual fracture fragment. This article reviews the principles of fragment-specific internal fixation, discusses the biomechanical and clinical data supporting its use, and provides a description of surgical technique.
